| Schmidt parallel shaft coupling is a kind of coupling with unique structure and good transmission performance. So as to enable better domestic design selection, the study including its mechanism classification, Kineto-static analysis, efficient analysis, manufacturing methods, parameters selection and simulation analysis are presented in this thesis, which provide a sound theoretical basis to the independent design and selection for the type of coupling.A more accurate mechanism classification is acquired in this thesis by analyzing the composition and evolution mechanism of the Schmidt parallel shaft coupling. The equations between the number of redundant constraint, the number of degrees of freedom and the relationship between kinematic pair and phase are presented; the corresponding kinematic analysis is accomplished, which lay a sound foundation to subsequent mechanical analysis.Second, counting on mechanism inertial force, the establishment methods and ideas of deformation coordinate condition are analyzed, the Kineto-static analysis and efficiency analysis are acquired, the cause of mechanism choke, the existence of cycle power are discovered; The design principles of dimensional parameters are given based on analysis of its impact on mechanism efficiency; the corresponding manufacturing and processing methods are put forward, the study on the effect of types of manufacturing errors to forces applied on mechanism are discussed; For the existence of cycle power, the corresponding parameters optimization approach are proposed.A three-dimensional solid model and the corresponding dynamic simulation analysis of Schmidt parallel shaft coupling are established using three-dimensional modeling and simulation software to verify the correctness of the aforementioned theoretical analysis.A new design and calculation equations of rod dimension, a new calculation method of equivalent moment of inertia and a design verification method for main parts are presented in this thesis. Aiming to the wear characteristics of sliding bearing, the comprehensive calculation method for performance coefficient and life-Speed coefficient of coupling are studied. The above work not only laid a reliable theoretical basis to the Independent design of the coupling of this type, but also improved the mechanism design and chosen approach, which can be an engineering application reference. |
